1/21. Studies on the functional disturbances of the papillary region using a pressure sensor.Investigation of the duodenal papilla and the bile duct by EPCG is essential to diagnose the organic and functional disturbances of the papillary region. We have developed a pressure sensor based on a semi-conductor in order to obtain a more objective observation of pathological conditions in the papillary region. Using a duodenofiberscope, the pressure sensor was placed on the tip of canula, and it was inserted into the papilla and measured the movements of the papillary region. The pressure sensor method was carried out in 18 normal subjects and 69 patients with various diseases. As the result of analysis of wave forms in normal subjects, regular wave form patterns were obtained. In about 71% of cases with biliary diseases irregular wave forms were observed. Irregular wave form patterns were also observed 40% of cases with cholecystolithiasis, while irregular patterns were revealed in 86% cases with choledocholithiasis. The pressure sensor method during for duodenofiberscopy is important diagnostic procedure for the determination of functional disturbances in the papillary region.- - - - - - - - - - ranking = 1keywords = cholecystolithiasis (Clic here for more details about this article) |
2/21. Posterior hepatic duct injury during laparoscopic cholecystectomy finally necessitating hepatic resection: case report.A case of bile duct injury during laparoscopic cholecystectomy finally necessitating right hepatic lobectomy is reported to re-emphasize the importance of preoperative and intraoperative assessment of the biliary tree. A 47-year-old Japanese woman underwent laparoscopic cholecystectomy for cholecystolithiasis. On postoperative day 5, fever and right hypochondralgia developed, and CT revealed fluid collection at the right hypochondrium. Percutaneous drainage was performed, and subsequent fistulography revealed a communication of the cystic cavity with the right posterior bile duct, which suggested injury of the aberrant hepatic duct. Conservative therapy, including the adaptation of fibrin glue, was performed, but closure of the fistula and cavity was not obtainable. Finally, a right hepatic lobectomy was performed four months after cholecystectomy. In this case, endoscopic retrograde cholangiopancreatography was unsuccessful preoperatively, and intraoperative cholangiography was not done. This case report re-emphasizes that the preoperative and intraoperative examination of the biliary tree is mandatory to avoid bile duct injury.- - - - - - - - - - ranking = 1keywords = cholecystolithiasis (Clic here for more details about this article) |
3/21. Accessory gallbladder originating from the right hepatic duct.A patient with symptomatic cholecystolithiasis underwent laparoscopic cholecystectomy after confirmation of the diagnosis by sonography. Intraoperative cholangiography was normal and the operation was completed laparoscopically. Due to the postoperative persistence of right upper abdominal pain, another sonogram and then an endoscopic retrograde cholangiogram (ERCP) were performed. To our surprise, an accessory gallbladder with a remaining gallstone was revealed. The accessory cystic duct was shown as arising directly from the right hepatic duct. The patient underwent a second laparoscopic cholecystectomy, but due to hemorrhaging the operation had to be converted to an open procedure. The two gallbladders and their corresponding cystic ducts and arteries were entirely separate. To our knowledge, this is the first publication of a duplicate gallbladder where the cystic duct arose directly from the right hepatic duct.- - - - - - - - - - ranking = 1keywords = cholecystolithiasis (Clic here for more details about this article) |
4/21. Gallstone ileus as a complication of cholecystolithiasis.biliary fistula and gallston ileus are rarely found. The diagnosis is difficult. Gallstone ileus requires urgent and appropriate surgical therapy. Enterolitotomy remains the gold standard of operative treatment for gallstone ileus, but additional procedures of one-stage cholecystectomy and repair of fistula are necessary. Some researchers advise first to resolve the gallstone ileus and then to perform the elective operation for gallstone disease in more ideal circumstances. Our case had clinical evidence of ileus, which was confirmed by radiological exam. Ultrasonographic examination performed before operation did not confirm the presence of gallbladder; it did not detect a large stone located in the intestine. The patient, a 75-year-old woman, was operated on. During the procedure it was shown that the second part of the duodenum was involved in a scar and displaced to the hepatic hilus. There was no gallbladder; it was probably destroyed by a long-lasting vesicoduodenal fistula. cholangiography also did not detect the gallbladder. Biliary passage through the common bile duct was sufficient. The hole in the duodenum wall was sutured, and Kehr drain was inserted into the common bile duct. The gallstone was removed by incision of the intestine down to the obstruction. The postoperative period was complicated by a small suppuration of the laparotomy wound. Vesicoduodenal fistula present for a long time can lead to atrophy of the gallbladder. The one-stage procedure seems to be appropriate if biliary fistula and gallstone ileus are found.- - - - - - - - - - ranking = 4keywords = cholecystolithiasis (Clic here for more details about this article) |
5/21. Unexpected bile duct carcinoma presenting with port-site metastasis after laparoscopic cholecystectomy for cholecystolithiasis.On March 1, 1999, a 71-year-old woman was diagnosed as having cholecystolithiasis, for which she underwent laparoscopic cholecystectomy at a local hospital. Intraoperative cholangiography was not performed. No malignant lesion was detected in the gallbladder. In March 2000, a subcutaneous tumor was pointed out at the port site in her abdomen, and resected. Histological examination revealed metastatic adenocarcinoma. On detailed examination, endoscopic retrograde cholangiopancreatography (ERCP) revealed a tumor, about 2 cm in diameter, in the lower bile duct. On June 1, she underwent pylorus-preserving pancreatoduodenectomy at our institute, and several disseminated lesions were detected at the port site and in the abdominal cavity. There have been few reports of bile duct carcinoma that developed peritoneal dissemination caused by leakage of bile during cholecystectomy. Leakage of bile should be prevented during laparoscopic cholecystectomy, even in patients not diagnosed as having cancer preoperatively.- - - - - - - - - - ranking = 5keywords = cholecystolithiasis (Clic here for more details about this article) |
6/21. Bouveret's syndrome as a rare complication of cholecystolithiasis: report of a case.Bouveret's syndrome, which is gastric outlet obstruction caused by a gallstone in the duodenum or pylorus, is a very rare complication of gallstone disease. It occurs most commonly in women (65%), with a median age of 68.6 years. This disorder is usually treated by surgery, but it has also been successfully treated by endoscopy, with or without extracorporeal shock wave lithotripsy. The mortality rate has improved to 12% in recent years. Herein we report the case of a 76-year-old woman with Bouveret's syndrome, and review the literature on this unusual entity.- - - - - - - - - - ranking = 4keywords = cholecystolithiasis (Clic here for more details about this article) |
7/21. Staged and complete laparoscopic management of cholelithiasis in a patient with gallstone ileus and bile duct calculi.BACKGROUND: Gallstone ileus is an uncommon cause of small bowel obstruction, and its incidence peaks in elderly women. Although enterolithotomy has been accomplished laparoscopically, often using a laparoscopically assisted approach, controversy persists as to the indication, timing, and surgical approach to a cholecystectomy with closure of the cholecystoduodenal fistula. methods: We present the case of a 63-year-old woman with symptomatic cholecystolithiasis who presented with acute gallstone ileus and underwent an emergency laparoscopic enterolithotomy. Hypotonic duodenography during the follow-up period demonstrated a cholecystoduodenal fistula and previously unsuspected stones in the bile duct. The patient underwent an elective laparoscopic cholecystectomy with repair of the fistula, a concomitant bile duct exploration, choledocholithotomy, and primary bile duct closure. RESULTS: The patient enjoyed an uneventful recovery, and was discharged home on postoperative day 5 after her initial emergency surgery. Her recovery after the subsequent elective surgery was more expeditious, with a discharge from hospital on postoperative day 2 and a return to office employment 2 weeks later. CONCLUSION: In the good-risk patient, staged laparoscopic management of gallstone ileus and the associated cholecystoduodenal fistula is feasible and appears to be safe. In such patients, imaging of the biliary tree is essential to detect silent choledocholithiasis, which also may be managed concomitantly and safely by the laparoscopic approach.- - - - - - - - - - ranking = 1keywords = cholecystolithiasis (Clic here for more details about this article) |
8/21. Combination therapy of laparoscopic cholecystectomy and endoscopic transpapillary lithotripsy for both cholecystolithiasis and choledocholithiasis.This report describes five patients with cholecystolithiasis and choledocholithiasis who were treated by combination endoscopic extraction of common bile-duct stones with sphincterotomy (EST) and laparoscopic cholecystectomy (LC). Following this combination procedure the patients were relieved completely of obstructive jaundice and right upper quadrant pain, leaving only small trocar insertion scars made during the short course of hospitalization. The combination therapy of EST and LC will be recommended for this kind of patient as a minimally invasive procedure.- - - - - - - - - - ranking = 5keywords = cholecystolithiasis (Clic here for more details about this article) |
9/21. Symptomatic cholecystolithiasis after laparoscopic cholecystectomy.A 45-year-old woman was admitted to our hospital complaining of upper abdominal pain. Seven months earlier a laparoscopic cholecystectomy had been carried out and a solitary gallstone removed together with the gallbladder. The patient now suffered from pain of the same character but lower intensity compared to the situation before the operation. At admission there were no abnormal laboratory findings, especially no signs of infection or cholestasis. Ultrasound revealed a stone in a gallbladder-like structure in the right epigastric region. ERCP revealed an inconspicuous cystic duct stump and no pathological findings in the extra- and intrahepatic bile ducts. MRCP and CT showed a cyst-like structure in the gallbladder region containing a concrement. The patient was transferred to the Department of Surgery for exploratory laparotomy, and a residual gallbladder with an infundibular gallstone was removed. The recurrent upper abdominal pain was obviously caused by a gallstone redeveloped after incomplete laparoscopic gallbladder resection. Retrospectively it could not be discerned whether a doubled or a septated gallbladder was the reason for the initial incomplete resection.- - - - - - - - - - ranking = 4keywords = cholecystolithiasis (Clic here for more details about this article) |
10/21. Structural changes of the exocrine pancreas in a patient with cholecystolithiasis.The exocrine pancreas has been studied histologically, morphometrically, and ultrastructurally in a patient with cholecystolithiasis in comparison with three control patients free from gastrointestinal or pancreatic diseases. In the gallstone-bearing patient, acinar cells undergo a significant increase in the average cell area and average zymogenic area (i.e., the portion of acinar cell cytoplasm occupied by zymogen granules). In addition, these cells showed cytological signs of enhanced synthesis of secretory proteins and increased formation and release of zymogen granules. The findings concerning centroacinar/ductular cells are consistent with a significant increase in their number and average cell area that is associated with ultrastructural signs of enhanced functional activity.- - - - - - - - - - ranking = 5keywords = cholecystolithiasis (Clic here for more details about this article) |
